However, a source close to both later denied the claim, saying that while the two are indeed close friends, there is no hanky-panky going on.

"They went to dinner. They weren't all over each other. He's her trainer and they hang out," the insider told E! News. "They are not dating. They hang out and they are friends."

But where does Duff fall in all of this? She finally weighed in during an interview on Good Day New York and seemed to kinda, sorta confirm her relationship status.

"The last time you were here you were talking about going on Tinder.… And then I see pictures of you and some guy named Jason… have we found a little like in our life?" the host asked Duff, who blushed.

"We have [found a little ‘like’ with each other]. We’ve known each other for a really long time and he’s a great guy and we have a lot of fun together," she admitted. "It’s nice to have that excitement in my life."

And when the host asked Duff if she's "back in a relationship," she just giggled and shrugged. It looked an awful lot like a "yes."

In case that left any lingering doubts, Duff got serious about her relationship status in October, making it Instagram-official that she and Walsh are an item.

"Date night with J," she captioned a black and white photo of the two of them kissing, with a heart emoji added for good measure.

This is awesome for Duff, who though still friends with her ex Mike Comrie, has definitely moved on from any romantic feelings. And Walsh is a huge catch! He owns his own gym; he loves dogs — what's not to love about him?
